A comical toilet game. Involves sitting on top of the cubical separators of a communal toilet (most often in a public school) with your bottom aimed over the toilet bowl. You then empty your bowels from a height of 5-6 feet into the toilet. If a sufficient size log is produced the results is a massive splash down resembling a WWII navy battle.

Caution: Always employ a 'look out' before attempting.
